If you read the helpful error messages that Python provides, instead of
hiding them and printing a useless message "wrong", you might find out why
the failures are happening.

Get rid of the try...except and see what exceptions you get. Then you will
be in a better situation to decide which exceptions should be caught, and
which are bugs that need to be fixed, and which should be allowed through.
